Main highlights

Spreader lawn fertiliser: the spreader settings are on the packaging. If fertilising is watered after the lawn, there is no danger to the child and dog. The granules are dust-free.
Quick start effect: the lawn fertiliser has a quick visible starting effect. After fertilising, the lawn quickly turns green and gets its juicy green colour. Brings life into the garden.
Lawn instant fertiliser: targeted nitrogen blasts of the NPK complete fertiliser ensure even growth of the lawn and ensure an immediate lawn upgrade.
Lawn fertiliser summer: here we recommend fertilising 1-2 times at the end of May/early June and August with 20 g/m². Thanks to the high potassium content, the orchid fertiliser prevents dryness and extreme heat.
Lawn fertiliser spring: we recommend starting fertilisation in March / April with 30 g/m². The fertiliser strongly stimulates the desired root binding and is therefore an optimal spring fertiliser.
